Detail wise, Vergil didn't sleep with a prostitute. That entire thing has been spiraled out of control. In actuality, we just know he obviously slept with someone. Fortuna's townsfolk claimed this based on the fact no one knew of his mother. This was in the DMC4 Novel.

Don't know why people keep saying he slept with a prostitute. Townsfolk assumed it. We know he slept with a woman obviously.
